I see this has been hashed over before, but I can not for the life of me get a simple FTP upload to work. No error is thrown, connection tests successful, I can manually upload the same file to the same path with the same creds.
Looking at a packet cap, it seems the activity is trying to change directory to the NAME of the file and not correctly parsing the path string. Same results with root path upload, escaped slashes, backslashes, etc. Version 1.0.7495.12930 of the official FTP activities. Studio 2020.4
